John Browne was a star of UK business: tough, successful, and as boss of BP, the company that had been his life, a man who had the Midas touch.
Then it all came to an end. He was brought down three years ago by a gay affair. He went to court to try to suppress a newspaper story about it, and in a witness statement told a lie.
When he confessed the untruth, an extraordinary career at the very summit of business was over. Jim Naughtie talks to Lord Brown about his life, public and personal, described in his new memoir Beyond Business.
